Action *****UPDATE******PHASE 2 UPDATED - URGENT MEDICAL DEVICE CORRECTION This updated notification is intended to further clarify the Mandatory Customer Actions for the potential carryover issue identified on the following ACL TOP systems (previous URGENT MEDICAL DEVICE CORRECTION letter dated Feb 22, 2022), when running a specific reagent combination. E-mail communication to the Werfen Affiliate and International Group circulated on July 14, 2022.
